Mindi in Tempe, Arizona on October 19, 1982. She left her home in the 2100 block of east University Avenue and walked her two stepsisters to school. When her stepsisters returned home, Mindi was gone and the front door was open. There were no indications of a struggle, and Mindi's purse, identification and other belongings were left behind. The last person known to have seen Mindi was a clerk at the Circle K convenience store on the corner of University and Price; the clerk saw her make a phone call and leave. She has never been heard from again.

Mindi's mother was murdered when Mindi was two years old. Police suspected her father, Allen Chambers, but he was never charged for lack of evidence. Mindi lived with Allen's mother and then with an aunt while Allen was serving time in prison for assault. He took her back after he got out of prison, when she was five. Three days before her 1982 disappearance, Mindi told the police that Allen had been molesting her for the past five years. Child Protective Services (CPS) immediately placed her in the care of her stepmother, who was divorcing Allen at the time. Then she disappeared.

No one reported Mindi missing until 1995. Her relatives stated she had a history of running away and they thought she had simply walked out of her life to escape her problems. CPS apparently dropped their investigation against her father within a short time. He died in a car accident in 1994.

Foul play is suspected in Mindi's disappearance. Her case remains unsolved.
